The percentage of the votes did Francisco receive is = 2%
Given that:
Four candidates participated in a school election.
Bianca received 1/2 of the votes
Chelsea received 0.28 of the votes
Darnell received 20% of the votes
Francisco received the rest of the votes.
Solution:
We know that the sum of all the votes received by the candidates is 100%.
Bianca received 1/2 of the votes
Chelsea received 0.28 of the votes
Darnell received 20% of the votes
Francisco received the rest of the votes.
Therefore, the sum of the votes received by Bianca, Chelsea, Darnell, and Francisco is:
Bianca + Chelsea + Darnell + Francisco = 1/2 + 0.28 + 20% + Francisco%
We know that the sum of all the votes received by the candidates is 100%.
Bianca + Chelsea + Darnell + Francisco = 100%
Converting Bianca's fraction to percent, we get:
Bianca = 1/2 × 100%
Bianca = 50%
Now substituting the values in the expression we get:
50% + 28% + 20% + Francisco% = 100%
Simplify the expression by adding 50%, 28% and 20%
50% + 48% + Francisco% = 100%
98% + Francisco% = 100%
Now we can solve for Francisco by subtracting 98% from each side.
100% - 98% = Francisco%
2% = Francisco%
Hence, Francisco received 2% of the votes.

The pair of points (7,4) and (3,y) lie on the same line with a slope of 1/4 , what is the value of y?
- CAN SOMEONE PLEASE HELP I NEED THE ANSWER NOW.
The value of y in the pair of points (7, 4) and (3, y), lying on the same line with a slope of 1/4, is y = 5. This is obtained by setting up and solving an equation using the slope formula.
The value of y can be determined by using the slope formula. The slope between two points (x1, y1) and (x2, y2) is given by (y2 - y1) / (x2 - x1). In this case, we have the points (7, 4) and (3, y), with a slope of 1/4. Plugging in the values, we get (y - 4) / (3 - 7) = 1/4. Simplifying this equation, we have (y - 4) / (-4) = 1/4. Cross-multiplying, we get -4(y - 4) = 1(-4), which simplifies to -4y + 16 = -4. Solving for y, we subtract 16 from both sides, giving us -4y = -20. Dividing by -4, we find y = 5.

The surface area of a sphere is 4πr2, where r is the radius of the sphere. The cost of a sphere is 2 per square foot, so the cost of a sphere with radius r is 8πr2. Selim can spend 20 per sphere, so he can purchase a sphere with radius r such that 8πr2≤20. This inequality can be solved for r to get r≤8π20=2π5. The diameter of a sphere is 2r, so the maximum diameter of the spheres Selim can purchase is 22π5=10π≈3.162 feet.
How do you find the hight of the equation v=pi*r^2*h/3
The formula of height h = (3v) / (π * r^2)To find the height (h) of a cone given the volume (v) and the radius of the base (r), we can rearrange the equation v = (π * r^2 * h) / 3.
By multiplying both sides by 3 and dividing by π * r^2, we isolate the variable h and obtain the formula h = (3v) / (π * r^2). Substituting the appropriate values for volume and radius into this equation allows us to calculate the height of the cone.
To solve for the height (h) in the equation v = (π * r^2 * h) / 3, we first multiply both sides by 3 to eliminate the fraction. This results in the equation 3v = π * r^2 * h. Next, we isolate the variable h by dividing both sides of the equation by π * r^2, giving us the formula h = (3v) / (π * r^2). By substituting the known values for volume (v) and radius (r) into this equation, we can calculate the height (h) of the cone. It is important to ensure that the units for volume and radius are consistent and compatible to obtain the correct result.

There are three paths through a triangular park. Each path connects the midpoint of one side to the opposite corner. The paths meet at point P, which is the centroid
Find PS and PC when SC = 24000 feet
PS and PC are both equal to 16000 feet when SC is 24000 feet. These lengths are determined based on the relationship between the centroid and the midpoints of the sides in a triangle.
In a triangular park, with point P as the centroid, if SC (one of the sides) is equal to 24000 feet, the lengths of PS and PC can be determined.
To find the lengths of PS and PC, we need to consider the properties of a centroid in a triangle. The centroid divides each median into two segments, with the ratio of 2:1.
In other words, the distance from the centroid to the midpoint of a side is two-thirds of the length of the entire median.
In this case, since SC is equal to 24000 feet, PS and PC can be calculated as follows:
PS = (2/3) * SC = (2/3) * 24000 = 16000 feet.
PC = (2/3) * SC = (2/3) * 24000 = 16000 feet.

The area of a rectangle is 384 square inches and length is 8 inches greater than width. What are the dimensions
The dimensions of the rectangle are 16 inches in width and 24 inches in length.
Let's assume the width of the rectangle is x inches. According to the problem, the length is 8 inches greater than the width, so the length can be represented as (x + 8) inches.
The formula for the area of a rectangle is length multiplied by width. In this case, the area is given as 384 square inches. So, we can set up the equation:
Length * Width = Area
(x + 8) * x = 384
Expanding the equation:
x^2 + 8x = 384
Rearranging the equation to solve for x:
x^2 + 8x - 384 = 0
We can solve this quadratic equation by factoring or using the quadratic formula. Factoring it, we find:
(x - 16)(x + 24) = 0
So, x = 16 or x = -24.
Since dimensions cannot be negative, we discard the negative solution. Therefore, the width of the rectangle is 16 inches.
Substituting this value back into the equation for the length:
Length = x + 8 = 16 + 8 = 24 inches
Hence, the dimensions of the rectangle are 16 inches in width and 24 inches in length, which gives an area of 384 square inches.

Jen traveled from Boston to Cape Cod at 60mph. On her way back, there was a lot of traffic, so her return trip took 3 times as long. What was Jen's average speed?
Please answer
Jen's average speed for the entire round trip, including the outbound and return trips, is 30 mph.
To determine Jen's average speed for the entire round trip, we need to calculate the total distance traveled and the total time taken.
Let's assume the distance between Boston and Cape Cod is "d" miles.
For the outbound trip from Boston to Cape Cod, Jen traveled at a speed of 60 mph. The time taken for this leg of the trip is given by:
Time = Distance / Speed
Time = d / 60
For the return trip, it took Jen 3 times longer due to heavy traffic. Therefore, the time taken for the return trip is 3 times the time taken for the outbound trip:
Time for return trip = 3 * (d / 60) = (3d) / 60
The total time for the round trip is the sum of the outbound and return trip times:
Total Time = d / 60 + (3d) / 60 = (d + 3d) / 60 = 4d / 60 = d / 15
The total distance for the round trip is twice the distance from Boston to Cape Cod:
Total Distance = 2d
Now, we can calculate Jen's average speed by dividing the total distance by the total time:
Average Speed = Total Distance / Total Time
Average Speed = 2d / (d / 15)
Average Speed = 2 * 15
Average Speed = 30 mph
Therefore, Jen's average speed for the entire round trip, including the outbound and return trips, is 30 mph.

a blueprint of a house is drawn using a scale of 1/4 in = 3ft. If the bedroom of the actual house is 16 by 12 in, what are the dimensions of the bedroom of the blueprint
The dimensions of the bedroom in the blueprint are approximately 1/9 ft by 1/12 ft.
To find the dimensions of the bedroom in the blueprint, we can use the given scale of 1/4 in = 3 ft.
First, let's convert the dimensions of the actual bedroom into feet:
Length of the actual bedroom = 16 in * (1 ft / 12 in) = 16/12 ft = 4/3 ft
Width of the actual bedroom = 12 in * (1 ft / 12 in) = 12/12 ft = 1 ft
Now, let's use the scale to find the dimensions of the bedroom in the blueprint:
Length of the bedroom in the blueprint = Length of the actual bedroom * Scale
Length of the bedroom in the blueprint = (4/3 ft) * (1/4 in / 3 ft)
Length of the bedroom in the blueprint = 4/3 * 1/12
Length of the bedroom in the blueprint = 4/36
Length of the bedroom in the blueprint = 1/9 ft
Width of the bedroom in the blueprint = Width of the actual bedroom * Scale
Width of the bedroom in the blueprint = (1 ft) * (1/4 in / 3 ft)
Width of the bedroom in the blueprint = 1 * 1/12
Width of the bedroom in the blueprint = 1/12 ft

The width of the rectangle is represented by n-7, so we have 2 sides of length (n-7). To calculate the perimeter, we add up the lengths of all four sides: (2n+8) + (2n+8) + (n-7) + (n-7). Simplifying this expression, we get 6n + 2, which is the polynomial in standard form for the perimeter of the rectangle.

What number should be added to (-5)/8 so as to get 5/9
Therefore, the value that needs to be added to (-5)/8 in order to get 5/9 is -5/72.
To get 5/9, what number should be added to (-5)/8?
We can begin the solution by adding "x" to (-5)/8. Then, we will have:((-5)/8) + x = 5/9
The next step is to isolate the variable x, which is accomplished by subtracting (-5)/8 from both sides. The equation becomes:(-5/8) + (5/9) = x
We'll need to find a common denominator for this expression:
((-45)/72) + (40/72) = xSimplifying, we get:
((-45) + 40)/72 = x(-5)/72 = x

The expression (y to the power of 20)(y to the power of −5)2i s equivalent to yn. What is the value of n?20010-20030
the value of n remains indeterminate in this case.To find the value of n in the expression (y^20)(y^-5)^2i equivalent to yn, we can simplify the expression first.
Starting with (y^20)(y^-5)^2i, we can simplify the exponent by multiplying the exponents of y:
(y^20)(y^-5)^2i = y^(20 + (-5 * 2))i = y^(20 + (-10))i = y^10i.
Now, we can equate this simplified expression to yn:
y^10i = yn.
To find the value of n, we can compare the exponents:
10i = n.
Since the imaginary unit i represents the square root of -1, and the exponent in this case is not purely real, we cannot find a specific value for n. Therefore, the value of n remains indeterminate in this case.

Shutterfly charges $20 to make a photo book with 15
pages. Each extra page costs $1. 65. The cost to ship the completed photo
book is $5. Write an expression to determine the total cost in dollars to
make and ship a photo book with x extra pages
The expression to determine the total cost in dollars to make and ship a photo book with x extra pages is: 25 + 1.65x.
To calculate the total cost of making and shipping a photo book with x extra pages, we need to consider the base cost, the cost of extra pages, and the shipping cost.
The base cost of making a photo book with 15 pages is $20.
Each additional page beyond the initial 15 pages incurs a cost of $1.65 per page.
Therefore, the cost of x extra pages would be 1.65x.
The shipping cost to ship the completed photo book is a fixed $5.
To calculate the total cost, we add the base cost, the cost of extra pages, and the shipping cost together:
Total Cost = Base Cost + Cost of Extra Pages + Shipping Cost
Total Cost = $20 + $1.65x + $5
Total Cost = $25 + $1.65x
Thus, the expression to determine the total cost in dollars to make and ship a photo book with x extra pages is 25 + 1.65x.

The function that represents the parent function vertically stretched by a factor of 3, reflected over the x-axis, and translated right 2 units and up 4 units is g(x) = 3∣x - 2∣ + 4.
This can be explained as follows:
In the parent function ∣x∣, the absolute value of x ensures that the graph is reflected over the x-axis, resulting in a V-shaped graph in the positive y-axis region. By replacing x with (x - 2), we achieve a horizontal translation of 2 units to the right. Next, multiplying the absolute value term by 3 vertically stretches the graph by a factor of 3, making the V-shape narrower and taller. Finally, adding 4 to the function translates the graph upward by 4 units.
Thus, the function g(x) = 3∣x - 2∣ + 4 combines the vertical stretching, reflection, and translations described above to match the given criteria.
